1. Mechanical life: The mechanical life of the waterproof connector refers to the number of insertion and removal life, and the industry standard is usually specified as 500 to 1000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the waterproof connector should not exceed the specified standard value, which is not much different from the plastic case.

2. Electrical performance: rated voltage, rated current, contact resistance, insulation resistance, etc. according to the specified standard value, this metal is the same as the plastic casing.
3. Environmental parameters: Environmental parameters mainly include ambient temperature, humidity, temperature change, atmospheric pressure and corrosive environment. The environment in which the waterproof connector is used during storage and transportation has a significant impact on its performance. Therefore, it is better to select the corresponding metal casing according to the actual environmental conditions.
4. Termination method: The termination method refers to the connection method of the hardware contact parts of the waterproof connector male and female connectors and the wire and cable. The metal is the same as the plastic case.
Comprehensive analysis, in addition to the need for joints with shielding, metal and plastic shells have little difference in performance. At present, the metal casing has certain advantages in hardness and strength, and the plastic has a lower cost relative to the metal casing, and the structure is more reasonable.
